  • Patent number: 8165118
    Abstract: A system for facilitating voice calls over a content centric network (CCN) receives from a CCN user an expressed interest in receiving voice calls directed to the CCN user, wherein information in the CCN can be addressed, located, and disseminated by its content identifier and wherein data packets in the CCN are self-authenticating. Next, the system receives from a second network a packet for a voice call directed to the CCN user. The system then forwards to the CCN user the packet received from the second network with a CCN identifier corresponding to the interest expressed by the CCN user and forwards a packet from the CCN user for the voice call to the second network.

  • Patent number: 8023654
    Abstract: A method for securing human to human communication over a network includes receiving, by a first computer, an incoming authenticated data stream from a second computer over a first communication channel, the incoming authenticated data stream having been computed using an incoming digital experiential data stream and a first imprint, and extracting the first imprint from the incoming authenticated data stream. The incoming authenticated data stream is then presented for sensory experience by a human. An outgoing digital experiential data stream is then input and the method computes a second imprint associated with the first computer and computes an outgoing authenticated data stream using the outgoing digital experiential data stream and the second imprint. A second communication channel is then secured from the first computer to the second computer using the first imprint, the second communication channel suitable for sending the outgoing authenticated data stream to the second computer.

  • Patent number: 6873944
    Abstract: A method of real time collision detection between geometric models includes the steps of identifying a current tracking point of a force feedback device colliding with a mesh model of the geometric model and identifying a current triangle associated with the current tracking point, wherein the force feedback device is operatively connected to a computer system. The method also includes the steps of determining a new tracking point of the force feedback device colliding with the mesh model by approximating the new tracking point from the current tracking point and the current triangle, and determining a state of the new tracking point and a known state using the new tracking point and the state of the previous tracking point, wherein the state is inside, on an edge or on a vertex of either the current triangle or a new triangle.

  • Patent number: 5694013
    Abstract: A method for providing a haptic interface between a user held physical device and a computer generated parametric surface determines if a collision has occurred therebetween. If a collision has occurred, a force to apply to the physical device is determined and a force actuation mechanism is activated so as to produce the force at the physical device. If a collision has not occurred, the force actuation mechanism is deactivated. The method is repeated as the physical device is moved through a virtual space in which the parametric surface is modeled. The physical device is capable of transmitting forces in at least three degrees-of-freedom via the force actuation mechanism which is connected thereto. A human operator holding the physical device can thus interact with the surface, which may be a CAD generated surface.
